Drivewear lenses are capable of sensing and reacting to varying light conditions both outside and behind the windshield of the car. Drivewear lenses provide the wearer with the appropriate visual solution for all weather conditions, from bright sunlight accompanied by intense, blinding glare, to overcast bad weather conditions. Drivewear lenses protect the eyes form glare through polarization and enhance and protect vision through photochromics which respond to both visible and UV light.
- LOW LIGHT CONDITIONS, OVERCAST
High Contrast Green/Yellow Color. Designed to maximize useful light information reaching the eye. POLARIZED to remove glare that would otherwise DESTROY vision in low light conditions. This color has been thought in order to maximize the total information to the eyes’ visual receptors at low lighting/overcast conditions. The high contrast polarizer works in every lighting condition to remove blinding glare and inhance visual acuity.
- BEHIND THE WINDSHIELD OF A CAR, BRIGHT LIGHT
Copper Color. Designed to block out exceeding light and to enable the spotting of road signs, pointing out red and green colors. POLARIZED to block out blinding glare and have optimum visual acuity for safe driving. One of the characteristic features of Drivewear is that they are the only photochromatic lenses that darken behind the the windshield of the car. If exposed to sunlight, the Drivewear lenses turn into a copper color which many consider the best color for a driving . This should not surprise, as Drivewear color has been thought to remove exceeding light and to allow the driver to provide good traffic signals recognition.
- INTENSE LIGHT CONDITIONS, OUTDOORS
Dark Reddish/Brown Color. Designed to maximise filtration of excess light so that the eye does not get satured. POLARIZED to provide maximum comfort in high light conditions. In outside conditions, Drivewear lenses is activated by visual and UV light and turn into a dark red/brown color. This color has been designed in order to provide maximum filtration of exceeding light and provide the best protection from intense sunlight and blinding gare. Brown lenses allow an excellent spotting of the colors, ponting out especially green colors. As green is the most common color in nature, its emphasising represents an extraordinary visual experienxce.
- Overcast – Low light conditions.
In low light conditions, Drivewear lenses provide a high light transmission maximalizing the number of informations reaching visual receptors of both eyes. The result is the best possible visual acuity in these conditions of low lighting conditions. In this state, the molecule allows all visible light to come through the lens. High contrast polarized removes glare, which otherwise would destroy vision in low light conditions. In this state, Drivewear lenses block 100% UV A and UV B light. This is one advantage of being Activated by Transitions(TM). Drivewear lenses turn into high contrast green/yellow color. Obviously, there are no better lenses to face overcast or low light conditions, both outside and inside a vehicle.
- Bright light – Behind the windshield.
In bright light conditions behind the windshield of a car, Drivewear lenses provide lower overall transmission to control light intensity for optimum visual acuity. Drivewear lenses promote preferential activation of the eye’s red cones (and to a lesser extent, green cones). The result is the best possible vision at these higher light levels. Drivewear’s high contrast polarizer is absolutely essential behind the windshield of the car, because it blocks out blinding glare, one of the most dangerous of all driving hazards.Under these conditions, the Drivewear lenses turn a copper color which many feel is the optimum color for a driving lens. This unique behind-the-windshield response protects against bright light and glare and provides better sensitivity to the “visual signal” that is vital for safe driving.
- Bright light outdoors – Outside intense light conditions.
In outside bright light conditions, the eyes’ visual receptors, the rods and cones, can easily get “overpowered” and “oversaturated” with light. The Drivewear lens is designed for maximum filtration of this excess light. Under these bright outside conditions, it achieves its maximum dark color. Here again, it is important to provide maximum protection from blinding glare, and only polarized lenses can do this. Drivewear is designed to provide maximum comfort to the wearer in these high outdoor light conditions.
Hi-Performance 1.74 Aspheric is the thinnest organic material, which is available in the current market; The Hi-Performance 1.74 lense, such as the Essilor Lineis 1.74, has been created in particular to satisfy the esthetic and comfort needs.
This material is particularly suggested for all users, who are very carefull at the esthetic aspect and at the quality. It is also suitable for high diopters. The advantage of Hi-Performance Aspheric 1.74 is a lense with high index in elastic organic material, which is distinguished by an high visual performance.

The human visual system automatically compensates for the overall colour shift that coloured filters produce. It’s why a photograph of a landscape lit by the setting sun looks much more orange than one remembers it at the time. Lens Technology named this effect Chromatic Adaptation. During the development, scientists measured the residual colour shift created by a specific tint after the “Chromatic Adaptation” had taken place. With that information, a Colour Rendering Index chart for this tint could be created. The Index uses a series of vectors on a colour chart to shows how wearers perceive colour with and without a tinted lens. As the diagram above shows, as long as the post Chromatic Adaptation shift remains within the same colour area, perception of colour remains largely unchanged. Our Lens Technology has developed a range of colors, which make the Chromatic Adaptation easier, enabling the restitution of colors in a natural way.

Another innovation in the Sun Lens range comes with the launch of polarising corrective lenses. In addition to providing protection against the effect of UV light, GiarreTechnology’s Polarising lenses at last give effective protection against the glare caused by reflected sunlight. They represent a real step forward in terms of quality of vision and are suitable to use in outdoor activities. A large amount of light coming into the eyes comes from polarised sunlight being reflected by smooth horizontal surfaces such as water, snow, ice, wet road surfaces, windshields etc. This causes a certain amount of glare, and reduces contrast as well as altering our perception of colour and shape. GiarreTechnology Polarising lenses are designed to cut out glare by eliminating reflected light through the use of a special polarising filter. Unlike standard sun lenses, GiarreTechnology Polarising lenses only let useful light go through.
- Glare reduction and improved contrast.
- Greater visual comfort.
- Enhanced colour perception.
- 100% UVA/UVB protection
- Polarising lenses offer increased safety.They eliminate the glare produced by reflections on wet road surfaces, dashboards and other cars.
- Ideal for all spectacle wearers, who participate in outdoors activities or with light-sensitive eyes.
Dynamic Transitions lenses are distinguished by their wide range of models and advanced materials, can be assembled on most of the frames present on the market and therefore meet the tastes and the full needs of the wearer. The peculiarity of these lenses is that they darken outdoors but return clear indoors and at night. Weather clear or in darkening process the Transitions lenses ensure 100% protection from harmful UVA and UVB and greatly reduce the effects of reverberation. Transitions lenses come in two colors: brown and grey, are equipped with advanced anti-reflection, antistatic and anti-scratch treatment, and therefore offer a clearer vision to the wearer.
